Is radioactive dating an exact process

The rules are the same in all cases; the assumptions are different for each method.To explain those rules, I'll need to talk about some basic atomic physics. Hydrogen-1's nucleus consists of only a single proton.Uraniums abbreviation is U, so uranium-238 can be more briefly written as U238.

For example, hydrogen-1 and hydrogen-2 are both nuclides of the element hydrogen, but hydrogen-1's nucleus contains only a proton, while hydrogen-2's nucleus contains a proton and a neutron.

To keep it short, a nuclide is usually written using the elements abbreviation.

I found several good sources, but none that seemed both complete enough to stand alone and simple enough for a What is radiometric dating?

Simply stated, radiometric dating is a way of determining the age of a sample of material using the decay rates of radio-active nuclides to provide a 'clock.' It relies on three basic rules, plus a couple of critical assumptions.

Young-Earth creationists -- that is, creationists who believe that Earth is no more than 10,000 years old -- are fond of attacking radiometric dating methods as being full of inaccuracies and riddled with sources of error.When I first became interested in the creation-evolution debate, in late 1994, I looked around for sources that clearly and simply explained what radiometric dating is and why young-Earth creationists are driven to discredit it.Protons and neutrons together are called nucleons, meaning particles that can appear in the atomic nucleus.A nuclide of an element, also called an isotope of an element, is an atom of that element that has a specific number of nucleons.Radiometric dating methods are the strongest direct evidence that geologists have for the age of the Earth.All these methods point to Earth being very, very old -- several billions of years old.

Then again, the rest of the movie leans heavily on that shtick too, so there's no reason the computer scenes should be any different. The Net (1995)Films about computer use run the risk of being visually dull and predictable, but The Net typifies another problem of the genre: obsolescence. But the weakest pair-off of the lot comes when Owen and Law, unaware of each other's identities, wind up in a "London Sex Anon" chatroom, with Law pretending to be a woman ("blonde. epic tits.") and demanding "sit on my face fuckboy." Director Mike Nichols handles all this with dry comic restraint; both men read and type with silent fixation and casually amused expressions, as if mildly aroused but not wanting to commit to more.
